  • the essence of the invention is to provide a turntable rotatably mounted in the housing concentric to the central axis for setting the deviating from the local time zone time zone, which is selectively adjustable by means of a housing arranged on the pusher clockwise and counterclockwise stepwise.
  • the pusher can be actuated along a radially oriented pusher axis, wherein the pusher drives the turntable via a gearbox integrated into the housing.
  • the transmission has two partial transmissions, which are mirror images of a passing through the pusher axis center plane and communicate with the turntable, and that the pusher for adjusting the turntable depending on the selected direction of rotation can be brought into engagement with one of the partial transmission.
  • the turntable preferably has on a visible from the outside scale surface on a 24h division; and the pusher moves the turntable in one or the other direction of rotation in 15 ° increments.
  • a preferred development is characterized in that the pusher for selecting the engagement in one of the partial transmissions is rotatable about the pusher axis, wherein the pusher can assume a first rotational position, in which he is in engagement with the one partial transmission, and occupy a second rotational position can, in which it is in engagement with the other partial transmission that the pusher between the first rotational position and the second rotational position can assume a neutral third rotational position in which it is disengaged from both partial transmissions, and in that the pusher in the rotational positions each latching is held.
  • each of the sub-gear has a gear designed as a ratchet wheel, in which the pusher in the first or second rotational position when pressing with a shift finger engages in a tangential direction, and that the shift finger on the pusher spring back to the pusher axis is stored.

  • Operation is further facilitated when markings are made to visualize the particular rotational position of the pusher on the pusher.
  • each of the partial transmissions has a plurality of shafts with a pinion gear and pinions seated on the shafts, that the pinions are mounted on each of the shafts by frictional engagement, and that the pinions on each shaft to prevent slippage are additionally positively connected to the pinion, wherein for the production of the positive connection between the pinion and the pinion of a shaft of the pinion in the axial direction extending pin, with which it engages in a corresponding radial groove in the pinion.
  • a further embodiment of the invention is characterized in that each of the partial transmission has securing means which prevent rotation of the partial transmission with the pusher not actuated, wherein the securing means comprise a pinion rotating with the partial transmission, in whose tooth spaces a tangential spring leaf with one at the free end arranged latching crest engages latching.
  • the pinion is preferably arranged together with the ratchet wheel on a common shaft.
  • Another embodiment provides that the turntable between the housing and a screwed onto the top of the housing glass holder is mounted, and that the turntable on the bottom has a ring gear, with each of which an output-side pinion meshes in each of the partial transmission.
  • an annular detent contour is formed with a 15 ° pitch, and the detent contour opposite locking means are provided in the housing or in the transmission, which cause a locking of the turntable in 15 ° increments.

The stroke of the pusher 16 is thereby converted by the transmission 15 in a rotational movement.
  • FIGS. 15 and 16 Turntable 14 shown in detail has on the top of an externally visible annular scale surface 51, which is provided with a 24h division.
  • the transmission 15 is designed so that per pressure actuation of the pusher Turntable moved by 15 ° and so in connection with a world time hand, not shown, causes a handover by a time zone.

  • a pinion 23, 25 and 27 is arranged on each of the shafts 21, 22, 24, 26, . Since considerable forces act on the transmission 15 through the pusher 16, and the pinions 23, 25 and 27 are fastened on the shafts 21, 22, 24 and 26 only by frictional engagement, the pinion of a shaft with the respective toothed drive additionally becomes positively positive coupled, as in Fig. 3-5 for the shaft 21 and the pinion 23 is shown.
  • the toothed drive of the shaft 21 comprises a ratchet wheel 56 with asymmetrical teeth 57, which play a decisive role in cooperation with the pusher 16.
  • the pinion according to 3 and 4 a plurality of axially extending pin 33, with which it engages in a corresponding radial groove 32 in the pinion 23.
  • This additional Formschiuss two located on a shaft gears or pinion can be used with advantage in other cases, where a slip between the gears must be safely avoided when high forces occur.
  • the structure of the pusher 16, the Fig. 6-8 The pusher, which has a stroke of approximately 1 mm, 16 comprises a bearing sleeve 34, with which it is inserted into the housing 11.

  • a crown 35 is rotatably mounted about the pusher axis 59, which is rotatably connected to the bolt 36.
  • a pusher head 37 is screwed with a threaded piece, which serves as an actuating element for the pusher 16.
  • the pusher head 37 is held by means of a spacer sleeve 41 at a distance from the bolt 36.

  • the hole is closed with a locking screw 39.
  • the shift finger 38 which has a chamfer on the top of the protruding part, comes - when the pusher is in the correct rotational position - when pressing the pusher 16 with the teeth 57 of the ratchet wheel 56 (FIG. Fig. 3, 5 ) and rotates the ratchet 56 by a certain angle further. This movement is transmitted via the respective partial transmission 15a, b on the turntable 14 and causes a further rotation of the turntable 14 in 15 ° increments.

  • a cylindrical pin 44 is inserted transversely to the pusher axis 59. If the pusher 16 is in an intermediate position, the pin 44 slides without much resistance on the sliding surface 46 of the bearing sleeve 34. On the other hand, if the pusher 16 rotates in one of the three excellent rotational positions, the pin will snap into the respective latching recess 47 due to the pressure of the compression spring 42 , 48 or 49 and fixes the pusher 16 in this rotational position.
  • Fig. 2 and Fig. 11-14 has each of the partial transmissions 15a, b additional securing means which prevent rotation of the partial transmission 15a, b with the pusher 16 is not actuated and at the same time ensure the assumption of a predetermined position regardless of the stroke of the pusher 16.
  • These securing means each comprise a pinion 23 which rotates with the partial gear 15a, b and in whose tooth spaces a tangentially lying spring leaf 28, which is screwed to the lower bridge 20 by means of screws 29, engages with a catch tip 58 arranged at the free end.
  • the mounted between the housing 11 and the glass holder 12 slewing ring 14 has on the underside a sprocket 53, with each of which an output-side pinion 27 in each of the partial transmissions 15a, b meshes ( Fig. 15 ).

  • the oblique flanks favor an automatic engagement of the turntable at the apex 54, even if the pusher 16 has not been fully depressed.
  • the detent contour 52 opposite locking means are provided in the housing 11 and the gear 15, which cause a largely independent of the stroke of the pusher 16 locking the turntable 14 in 15 ° increments.
